CEN/TS 16931-3-4:2026

This CEN Technical Specification (TS) contains the mapping between the semantic data model of an electronic invoice (EN 16931-1) and the UN/EDIFACT INVOIC syntax. For each element in the semantic model (including sub-elements or supplementary components such as Code List identifiers) it is defined which element in the syntax is to be used to contain its information contents. Any mismatches between semantics, format, cardinality or structure are indicated. Any rules to be followed when using the specific syntax are stated informally in this TS. If later versions of the UN/EDIFACT INVOIC support the semantics more accurately, this is indicated.
